GIN 0E DEEINTINGeIN.

To allee/ima t may concern.'

Be it known that l, WARREN H. NEsMrrH, a citizen of the vUnite-d States of America, and resident of Houston, in the countyT of Harris and State ofTeXas, have invented new and usefullmprovements in Gins or Delinting-Gins, of which the following is a specification.

This invention relates to kcotton gins and delinting gins, and particularly to saw. gins vof the kind having a gratefall', so-called, and

cluding the gratefall and the breast, with the permanently attached breast-hopper, or removing the breast and its hopper from the 'gratefalh after which the gratefall is swung 'forward and upward on hinges to afford access to thesaw cylinder.

When the breast is removed from the gratefall the seedsA contained in the roll-box have to be removed. All the adjustments of the breast are disturbed and there is also considerable loss which have beenremoved from'A the roll-box.

in the unlinted seeds There is also Va loss of time for the reason that whenv Vthe cylinder has been replaced in the linter and the gratefall restored to place the .breast has to be reattached to the grateful and readjusted, andthe roll-box `has to be illed'with fresh seed,vall of which takes time and entails loss in the production offiber. And if the breast and gratefall are removed from the machine together,

time is lost and difficulties are encountered v Y in reattaching the gratefallto the gin, with the saws projecting in proper position between the grates. f Y

j Moreover the feeder hoppers of gins 'as heretofore constructed have ybeen provided with magnetboards attached yto the feeders by a hinge in iixedlposition.' with the result that the magnet-board interferes with the raising of the gratefall to give access to the saw cylinder. y Access to the saw-cylinder to l attend .to the saws is required frequently to maintain efficiency of the gin,` but considerable loss of lint and a more important loss Specification `of Letters Patent;v

of time results from having to dismantle'the inachinein order to get at the` sawfcylinder.

Principal objects of the present invention are-to provide for quick access to the saws without emptying feeder hopper or breast 'and to provide a new construction in which the hinged breast, grate,`etc., can be swung clear of the saw-cylinder so as to permit the saw-cylinder to beremoved without having to take ofi the large feeder hopper at the top of the gin', or to remove the breast or the vroll-bor as a whole, or the magnet-board, from the gin. y

In the accompanying drawings,-

Figure 1 is a fragmentary side elevation of so Vmuch of agin as is necessary to illustrate the invention;

Fig'. 2 is a similar detail section showing the parts in another position.;

Fig. 3 is a vertical section inside one of the v ends of the feeder hopper; f Fig. i is a detail in4 perspective ofthe detachable breast hopper for'the top of the roll-box; and k l l Fig. 5 is ajdetail in front elevation showthe attaching means also illustrated in ig. 4. v ,v

The construction ofjthe frame 1, sawcylinder 2, brush 3, and bearings and axis Il for the saw-cylinder, may be the same as usual.

The roll-box comprises the usual heads 5, removable and adjustable front-board or breast 6, grate 7, andfloat-shaft 8, and may permanently attached thereto but is a cle-' tachable structureV presently mentioned in detail. Y

The'feeder hopper may b evof any desired be'the same as usual except thatthe hopper y 30 at the top of the breast or roll-box isnot or usual construction preferably comprisingV the end castings 10, back and side boards 11, and an inclined bottom 12, which as usual may be a board including bar-magnets 13l to prevent ironv or steel foreign objects from entering the roll-,box and injuring the saws.

The `hopper 10.11, is attached firmly to the i frame 1, and .includes bearings for feeder shaft 19. The magnet board 12, operative in the position illustrated inv Fig. 1, is pref- '.erably arranged to slide in ways 18 formed inthe ends 1.0,A andis provided with means for moving it backward and upward out of the Way. As shown, this means may comprise a shaft 14 and handfwheel 15 for pinions 16 engaging with, racks 17 on the Y. under side ofthe magnet board 12 for moving the board l2 to the Fig. 2.

The gratefall 5, 7,- is hinged as shown at position shown in 20. The construction and position of the end frames ll is such as to permit the gratefall to be swung upward as shown in Fig. 2, when the magnet-board 12 is ont ot the Way, and the gratefa-ll may lbe held in thisV position by hooks 21.

As usual Lcotton or cotton-seed lo'wing down the board 12 is taken through the opening in the top of the rolldiox 5, 6, 7 as tastk as the gin disposes of the seed and the lint cotton. This opening is provided with a. breast hopper 30.

As best shown in Fig. l according to the present .invention this breastV hopper is a` detachable structure con'iprising end castings 31 having lugs 29 to take Within the ends 5, and exterior clamp-irons 25, 25, and

Wing screws 26 for clamping the breast hopper 30, comprising the castings 31- and a front-board 32 screwed to the end castings 30, rigidly to the top oitV the breast. 'fo make the structure more rigid, integral lugs 27, 27, may project Vfrom the front of the end castings 3l. i'

When access vto the saw-cylinder 2 is desired, the breast 'hopper 30 is removed by loosening the screws 2G, the magnet board 12 vis run back, and the gratefall and breast are then lifted to the position shown in Fig. 2, and held up by the hooks 21. The saw-cylinder' 2 can then be rolled Yforward from its bearings as usual.` As will be clear from theV drawings, Without removing the breast-hopper 30V and withdrawing the inclined bottom l2, the roll-box could not be swung out of the way suiiiciently to admit ot the removal of the sawecylinder.

ldhat I claim is: i

l. A gin havingV a frame and. bearings therein for its driven ele-ments a hinged 7 ".3 gratetall and breast, a removable gmnmg .i element, a feeder-hopper xed on said trame. and a brcastliopper adapted to be removed Ward on'its hinge against the feedenhopper to admit of the removal of the saw-cylinder.

3.V A gin having a suitable trame, a rotary ginningil element,` a` feeder-hopper mounted on the trame, a roll-box compris- 'Ying` a. gratefall Vand breast pivoted on the fra-me, and an inclined bottom for the eede hopper' adapted to conduct theV contents of the hopper to an opening inthe top of the r0ll-boX, and means i''or withdrawing said inclined bottom backwardly .and upwardly whereby to permit the roll-box to be moved upwardly on its pivot 'for removal of the ginning element Without emptyingthe contents ot' the roll-box or feeder-hopper.

4. A gin having a frame and a saw-cylinder, a roll-box comprisingY a` gratefall and breast hinged for movement in respect to the saw-cylinder, a hopper-feeder mounted on the frame, an inclined sliding bottom for said hoppeiiieeder adz'ipted'to direct its contents into the top of Vthe roll-box when the roll-box and inclined bottom are positioned operatively, in combination with means permitting' said inclined bottom to be moved out of the Way when the roll-box is lifted about its hinge-pivot Y 5. vA gin hating a traine and saw-cylinder, a roll-box comprising a gratefall and breast hinged for movement Vin respect to the saw-cylinder, a hopper-feeder mounted on the trame, an inclined movable bottom for said hopper-feeder adapted to direct its contents into the topA oit the roll-box when the roll-box is positioned operatively, incombi-V nation with a` breast hopper adapted to receive said contents Whenthe parts are operatively positioned, said breast-hopper and inclined bottom being adapted; to be ifemoved to permit the roll-boi: to be swung upwardly to admit ci? saw-cylinder. A Y

6. A gin having' in combination, a hinged the removal olE said gratefall and breast, a feeder-hopper com- Y prising` an inclinedbottom board projecting at one side, and a handoperated shaft and gearing tor -withdrmving said board Within one side of the hopper and out ot' the wayA ot the gratetall and breast when lifted to an inoperative position. Y

'7. A removz-ible breast-hopper for `gine comprising end-pieces adapted to be cli-mopedv i on the roll-box and `connected together ,by another wall ort said breast-hopper.
